The project begins by drawing two basic distinctions. The first distinction is between forms of ideological discourse in general, which may not be critical in their orientation, and those forms of critical discourse which are historically self-conscious in their method. The formal antitype of all critical discourse is, in this view, the discourse of interpretation. The second distinction separates forms of critical thought from forms of critical discourse. Unlike the latter, forms of thought do not require for their existence the (...) operation of an explicit set of signs or system of objective articulation.One further introductory point is in order. I believe that the elementary forms of critical discourse should be divided into two large categories: the narrative forms, on the one hand, and the nonnarrative forms, on the other. Furthermore, I suggest that the nonnarrative forms—which are my chief concern in this paper—comprise four elementary types: the hypothetical ; the practical or injunctive ; the array; and the dialectic. I shall concentrate on the nonnarrative forms, and in particular on the array and the dialectic, for two reasons: first, one of these, the array, is not normally recognized as a form of critical discourse; and, second, both the array and the dialectic offer especially clear contrasts with narrative forms of discourse, both critical and noncritical.1 1. Some brief comments on the other two nonnarrative forms may be useful. Perhaps the best examples of a practical or injunctive form are furnished in a book like Euclid’s Elements, or any cookbook. The hypothetical form may be illustrated out of any number of classic works such as Sir Humphry Davy’s “On Some New Phenomena of Chemical Changes Produced by Electricity” and Michael Faraday’s “Electricity from Magnetism” . Jerome J. McGann is the Doris and Henry Dreyfuss Professor of Humanities at the California Institute of Technology. A new book, The Beauty of Inflections: Literary Investigations in Historical Method and Theory , continues the critical projects of his recent books The Romantic Ideology: A Critical Investigation and A Critique of Modern Textual Criticism . His most recent contribution to Critical Inquiry is “The Religious Poetry of Christina Rossetti”. (shrink)
